The Lowdown

Alright, folks, Rusty here. Let's have a look at what Jaconé has in store for us over the next couple of weeks.

Right off the bat, we've got a bit of a quiet start. The first decent surf doesn't really show up until Monday the 14th, so don't expect much before then. The water is sitting at a warm 72.1°, which is pretty much what you'd expect for this time of year.

Now, for the best waves on offer, you'll want to mark your calendars for Thursday the 17th. That morning, we're looking at a solid 5.6ft south swell with a 9-second period, combined with light east-southeast winds making for clean, cross-off conditions. The combined swell energy is a moderate 683, but it's the afternoon that really steals the show. Swell bumps up a touch to 5.9ft from the south, period stretches to 10 seconds, and energy jumps to a strong 1003. With a steady east breeze holding it clean, this is the standout session for experienced surfers. If you've got the skills, Thursday is your day.

Leading up to that, Monday the 14th offers a smaller but fun option. We've got a 3.6ft south swell, and the wind swings offshore from the northeast in the afternoon, with a solid 9-second period. Energy sits at a moderate 297, making for a clean and workable session.

Tuesday the 15th sees a drop in size to 3ft, with the wind turning onshore, so we'll skip that. Wednesday the 16th picks up again, with the afternoon pushing 4.9ft from the south and a long 12-second period, but the cross-onshore wind keeps things choppy. Energy hits a strong 1133, but it's a bit of a messy one.

Friday the 18th is a mixed bag. Morning brings 5.2ft south swell with offshore winds, but the wind is a moderate breeze at 15.5 mph, making it a bit of a handful. The energy is moderate at 617. The afternoon drops slightly, and the wind picks up even more, so it's not the cleanest.

After a bit of a lull, the following week has some interesting developments. Saturday the 26th is looking promising, with a 2.6ft south swell and a long 13-second period. Combined with light offshore winds from the east-northeast and clear skies, this is a very good option for a clean, glassy session. The energy is a moderate 536. Sunday the 27th morning offers a tiny 2.6ft east swell with glassy conditions, but it's small.

For the long-range, keep an eye on Saturday the 26th as the best bet in the second week. It's a little further out, so less certain, but the setup looks clean and fun.

Stay safe out there.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
